Title: Magnetic film core for thin-film magnetic head and production thereof
Inventor: KAMIMURA HIROHIKO
IPC: G11B5/31
Filed: 1989-09-21
Abstract: PURPOSE:To obtain the good magnetic film core for the thin-film magnetic head even if the width of a magnetic path is narrowed by sticking 2nd magnetic films having the magnetic anisotropy stronger than the magnetic anisotropy of a 1st magnetic film at both ends in the direction intersecting with the magnetic path direction of the 1st magnetic film. CONSTITUTION:The 1st magnetic film 5 is formed by an electroplating in a magnetic field on a metallic film 2 for electrodes erected with a resist 1 for a frame. Alumina 6 for a cover is formed in the part enclosed with the resist 1 for the frame on the 1st magnetic film 5 and thereafter, the magnetic film 5, resist 1, metallic film 2 and thin film 3 exclusive of the films covered with the alumina 6 are removed. The 2nd magnetic film 7 is stuck by an electroplating method on both side surfaces of the 1st magnetic film 5. Further, the alumina 6 for the cover is removed and the 1st and 2nd magnetic films 5 and 7 are heat treated to enhance the matching property. The good magnetic film core for the thin-film magnetic head is obtd. even if the magnetic path width is narrowed for the purpose of high-density recording in such a manner.

Title: Base for ball game
Inventor: IKEHARA ATSUYOSHI
IPC: A63B71/02
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a base for ball game eliminating a peeling of a cloth cover during runner's running in or sliding in, resisting staining, and facilitating stain removal. SOLUTION: A base for ball game is provided with a body 1 with a top face 1a and peripheral faces 1b made of rubber, and a cloth cover 2 covering the top face 1a and the peripheral faces 1b. The cover 2 is fixed to the body 1 by infiltrating the rubber from surfaces of the top face and the peripheral faces into the cover 2 and curing the rubber. The cover 2 is fixed to the body 1 securely because the rubber from the body 1 is penetrated between fabrics of the cover 2, thereby preventing a stain from infiltrating into the cover 2, and facilitating the removal of the stain attached to a surface of the cover 2.

Abstract: PURPOSE:To prevent the generation of residual strain and meandering without deteriorating productivity by specifying take-off tension during a time when the resin temperature of a molten resin sheet is lowered up to the softening point and increasing take-off tension by stages with the lowering of the resin temperature. CONSTITUTION:A molten resin extruded from an extruder 1 is kept within a range lower than the temperature of approximately the melting point and the softening point during a time when the molten resin is forwarded to a first take-off roll 3 through three rolls 2, and tension is adjusted within a range of 0.05-0.7kg/cm<2>, preferably 0.2-0.5kg/cm<2>. Residual strain is generated when the temperature is larger than said values, and the resin cannot be taken off when the temperature is smaller than those. The molten resin is kept within a range lower than the temperature of approximately the softening point and the thermal deformation temperature between the first take-off roll 3 and a second take-off roll 4, and tension is adjusted in 0.6-1.2kg/cm<2>. When the temperature is lower than said temperature, meandering is generated. The resin is taken up on a recoiler 5, but the temperature of the resin is the thermal deformation temperature or lower, and tension is regulated in 1.2-5kg/cm<2>. An adhesive state to the recoiler is lowered and productivity is deteriorated when the temperature is lower than said temperature, and rolling is generated and an adverse effect such as strain, blocking, etc., appears when the temperature is higher than the said temperature.

Title: Lead frame for resin sealed type semiconductor device
Inventor: SANO AKIRA
IPC: H01L23/50
Filed: 1988-10-03
Abstract: PURPOSE:To prevent a lowering of reliability and the development of package cracks which are caused by absorption of moisture by providing holes at both surfaces and rears of inner lead parts which are sealed in a mold resin. CONSTITUTION:Circular holes 8 are provided at both front and rear surfaces of inner lead parts 7 of a lead frame. When the lead frame is sealed with resin, a mold resin is introduced even into the holes 8 which are provided at both sides of the inner lead parts 7 and then, superior close contact is just made between the inner lead parts 7 and a mold resin layer 5. As a result, it becomes harder for spaces between the mold resin layer 5 and the lead frame as well as a semiconductor chip 3 to absorb moisture. Such a configuration improves the reliability of a semiconductor device; besides, the development of package cracks are prevented when the lead frame undergoes thermal stress.

IPC: H02P27/08
Filed: 1992-09-18
Abstract: PURPOSE:To allow cables among a servo control circuit, a servo amplifier and a servo motor to be integrated to one cable. CONSTITUTION:A cable 87 between the servo control circuit 11 and the servo amplifier 2 has a command signal line from the servo control circuit 11 and a feedback signal line from the servo motor 6. The command signal line consists of three PWM signal lines 21-23 whose number is reduced to half by using an invertor in the power control circuit of the servo amplifier 2, ground lines 24-26, one enable signal line 50 and other various signal lines. The other feedback signal line transmits a position feedback signal from the servo motor 6 via the servo amplifier 2. Since the signal line to be eliminated between the servo control circuit 11 and the servo amplifier 2 is used as the feedback signal line transmitting the position feedback signal from the servo motor 6, only one cable for connecting the servo motor 6 to the servo control circuit is required.
